SPECIFICATION forming part of Letters Patent No. '7 75,304, dated November 22, 1904.

Application filed January 31, 1903. Serial No. 141,309. (No model.)

To all whom it may concern.-

Be it known that 1, VINCENT A. IVIENUEZ, a citizen of the United States, residing at Memphis, Shelby county, State of Tennessee, have invented certain new and useful Improvements in Drop-Lights, of which the following is a specification.

My invention relates to certain new and useful improvements in vapor-lamps, and has especial reference to improvements in the details of the lamps and the extension for same.

The objects of my invention are to improve the details of the burner in general, the initial heater, the extension-check, and the make-up of the lamp.

I carry out these objects, as will be more fully set forth in the drawings, specification, and claims.

In the drawings, Figure 1 is a sectional elevation on the center line, showing the general outline of the lamp, with oil-tubes leading to the burners but not showing the burners. Fig. 2 is a sectional detail. Fig. 3 is a sectional elevation on the center line, showing the detail of the extension. Fig. 4 is a section on the line VIII VIII of Fig. 3 looking down. Fig. 5 is a section on the line IX IX of Fig. 3 looking in the direction of the arrow.

Referring now to the drawings, in which like parts are indicated by the same or like numerals in all the views, 1 is an oil-reservoir, which is permanently fastened by brazing at 2 and 3 to a tube 4, which extends downward and supports a T 5, having two or more openings 6, into which the supporting-tubes 7 for the burners (not shown) are screwed. The tube 4 extends beyond the T 5 and at its extreme lower end supports a frame 9, which carries a spring-balance drum 10.

11 is the drum-shaft, and 12 the spring.

.The frame 9 is fastened to the tube 4 by screws 13, which may be taken out if it is desired to remove the frame. WVithin the tube 4 is a second tube 14, on which the tube 4 slides and which has an annular lug 15 extending outward therefrom near its lower end and slidably fitting the interior of the said tube 4. A second annular lug'16 projects inward from the tube 4 at its upper end and fits slidably on the tube 14, so that when the tube 4 is drawn down these lugs slide, respectively, on the opposite tubes until they come together, limiting the downward motion. lVithin the tube 14 is a third tube 17, having an annular lug 18 at its lower end, which slides within the tube 14 and which, with an annular lug 19 at the upper end of the said tube 14, guides it and limits its downward motion. The tube 17 is supported by a loop 20, to which it is preferably fastened by screws 21, so that it may be easily removed, if necessity should arise. The lower end of each of the inner tubes is flared out trumpet-shaped to fit the interior of the tube surrounding it, making, with the lugs, 21. perfect guide.

22 is an ornamental casing to hide the loop 20.

The tube 4 moving upward slides, as above described, on the tube 14 until the lower end of the said tube comes against the screws 13, when it picks up the said tube 14, and the two slide as one on the tube 17 till they come against the casing 22, which stops them. To balance the weight of these moving parts, I make use of the spring-drum 10, mounted in the frame 9. This drum is connected with the supporting-loop by a rod 23 and a fiexible connector or cord 24, which is wound upon the drum by the action of the spring 12, Fig. 7, and which is forcibly unwound by pulling down the lamp.

25 is a roller to guide the cord 24.

In order to stop the drum 10, and therefore the lamp, at any desired point, I extend the arms 26 of said drum and provide cylindrical flanges 27 to serve as friction-drums, against which drums friction'shoes 28 bear. These shoes have a face of rubber or leather 29, which give a gripping hold on the drums 27. These shoes 28 are supported by a yoke 30, having guiding-lugs 31, which slide against the sides of the frame 9 and support the shoes. A shank 32 extends downward from the yoke and into a cylindrical hole 33, through the lower shank 34 of the frame 9. 32 is tapped to receive a rod 35, which projects downward therefrom, leaving, in effect, a shoulder 36 and which has a finger-grip 37 fastened to it. Its lower end is supported by a guide 38, carried by an ornamental pull 39.

This shank 9 Surrounding the rod 35 in the hole 33 is a compression-spring 40, which bears at its upper end against the shoulder 36 and at its lower end against a plug 41, screwed into the hole 38, and which spring holds the shoes 28 normally tightly against the friction-drum 27.

The balance-drum 10 and its frame is inclosed within a spherical shell, the upper half of which, 42, rests on the lower half 44, which lower half is held by a nut 45, screwed on a thread on the exterior of the shank 34, which is formed with a reduced suction 46 and shoulder 47 for this purpose. This nut may be entirely independent, as described, in which case the arms 48 of the ornamental pull are extended upward and brazed to the lower half 44 of the shell at 49. It is preferable, however, to connect the nut with the ornamental pull by an arm 50 integral therewith, which arm extends outward and forms a part of the arm 51. If this is done, however, the arms 48 and 51 do not touch the shell 44 and are not fastened to it. The ornamental bracket 52 is in either case made detachable from the shell at 53, as shown.

Oil is supplied to the burners through an independent tube 54, extending along the tube 4 and preferably coiled around it for ornamental effect. This tube extends upward to the lower surface of the reservoir 1, terminating, if the lamp is a gravity one, just within it at 55. If, however, the lamp is a pressurelamp, it is preferred that the tube 54 extend upward, curving over and extending thence downward to the lower portion of the reservoir.

56 is an air-filling tube having avalve 57 of the bicycle type at its lower end and extending upward thereform to a point above the liquid line, terminating in a valve-seat 58, on which a ball 59 rests as a valve. This ball is retained by a cage or sleeve 60, formed of a larger pipe surrounding the pipe 56 and having a contracted aperture 61 to prevent the ball being dislodged. This cage is preferably 45 slightly conical, so that the ball will have more space around it as it goes toward the mouth 61.

The tube 54, extending downward from the reservoir, enters the T 5 and distributes its oil through a channel 62 to the openings 63 opposite the lamp-feed tube-openings. From these openings 63 it passes into small feedtubes 64 within the supporting-tubes 17, and by these is carried to the burners.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a lamp extension, a supporting-loop, a tube attached thereto, tubes telescoping on said tube, a supporting-frame carried by the outermost tube, a spring-balance drum carried in said frame, a cord attached to said loop and said drum, said frame carrying a shouldered and threaded shank, a divided spherical casing inclosing said drum and frame, and a nut engaging the threads on said shank and supporting the lower half of said casing to permit access to said frame.

2. In a lamp-extension, a supporting-loop, a tube attached thereto, tubes telescoping on said tube, a supporting-frame carried by the outermost tube, a spring-balance drum carried in said frame, a cord attached to said loop and said drum, said frame carrying a shouldered and threaded shank, a divided spherical casing inclosing said drum and frame, and an ornamental pull having a nut integral therewith engaging the threads on said shank and supporting the lower half of said casing to permit access to said frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

VINCENT A. MENUEZ.
